  1. Phishing “In computing, phishing (also known as carding and spoofing) is a form of social engineering, characterized by attempts to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to "fish" for users' financial information and passwords. “ http://en.wikipedia.org/wiki/Phishing

  2. Phishing – In the Beginning • In the 1990s unethical AOL users created false accounts with “algorithmically generated credit card numbers — these accounts could last weeks or even months until new ones were required. AOL eventually brought in measures in late 1995 to prevent this, so early AOL crackers resorted to phishing for legitimate AOL accounts.” • Individuals involved in such measures were often those involved in illegal sale and distribution of boot leg software. • http://en.wikipedia.org/wiki/Phishing

  3. Phishing – In the Beginning • The phisher or cracker would “pose as an AOL staff member and send an instant message to a potential victim, asking the victim to reveal his or her password.” http://en.wikipedia.org/wiki/Phishing#Early_phishing_on_AOL Stutz, Michael: “AOL: A Cracker's Paradise?”, Wired News, January 29, 1998. • The phisher would use the now all to common technique of sending some kind of message to the unsuspecting AOL user asking to give “up sensitive information … include text such as "verify your account" or "confirm billing information". Once the victim had submitted his or her password, the attacker could then access the victim's account and use it for various criminal purposes, such as spamming.”

  4. Phishing – Moving on from AOL • In 1977 AOL adjusted its security policies making it very difficult for such illegal activities to occur. As a result these activities migrated elsewhere on the Internet. • Phishing is now unfortunately Everywhere! • Estimated losses from phishing from May 2004-May 2005 exceed three billion dollars to individuals and businesses in the US alone. • More than 1.2 million US citizens were effected. • http://en.wikipedia.org/wiki/Phishing#Early_phishing_on_AOL
